ATI Pathophysiology Final Exam
1. A nurse is teaching a patient about the use of raloxifene (Evista) for the prevention of osteoporosis. What is the primary therapeutic action of this medication?
- A. It decreases the absorption of calcium from the intestines.
- B. It decreases bone resorption and increases bone density.
- C. It increases the excretion of calcium through the kidneys.
- D. It stimulates the formation of new bone.
Correct answer: B
Rationale: The correct answer is B. Raloxifene, a selective estrogen receptor modulator (SERM), works by decreasing bone resorption and increasing bone density. This action helps in preventing osteoporosis by maintaining bone strength. Choice A is incorrect as raloxifene does not affect the absorption of calcium from the intestines. Choice C is incorrect as raloxifene does not increase the excretion of calcium through the kidneys. Choice D is incorrect as raloxifene does not directly stimulate the formation of new bone; instead, it primarily works by reducing bone loss.
2. Which of the following statements characterizes irritable bowel syndrome?
- A. Typically does not cause anemia
- B. Not generally associated with intestinal E. coli
- C. Can be associated with anxiety and/or depression
- D. Not often associated with bloody diarrhea
Correct answer: C
Rationale: Irritable bowel syndrome (IBS) is a gastrointestinal disorder characterized by abdominal pain, bloating, and changes in bowel habits. While IBS can lead to symptoms like diarrhea or constipation, it typically does not cause anemia (choice A), is not generally associated with intestinal E. coli (choice B), and is not often associated with bloody diarrhea (choice D). However, IBS can indeed be associated with anxiety and/or depression (choice C) due to the gut-brain axis, a bidirectional communication system between the gut and the brain. This association is well-documented in IBS patients, highlighting the importance of considering psychological factors in managing the condition.
3. A young man has received a diagnosis of androgen deficiency and has been prescribed testosterone. At clinic follow-up appointments, the nurse should prioritize which of the following assessments?
- A. Bladder ultrasound and urine testing for glucose and ketones
- B. Weight and measurement of blood pressure
- C. Hearing assessment and abdominal girth measurement
- D. Deep tendon reflexes and random blood glucose testing
Correct answer: B
Rationale: In a patient receiving testosterone therapy for androgen deficiency, monitoring weight and blood pressure is crucial. Testosterone therapy can lead to weight gain and hypertension, making regular assessments of these parameters important to detect and manage any adverse effects. Choices A, C, and D are not the priority assessments for a patient on testosterone therapy. Bladder ultrasound and urine testing for glucose and ketones, hearing assessment and abdominal girth measurement, and deep tendon reflexes and random blood glucose testing are not directly related to the common side effects or monitoring requirements of testosterone therapy.
4. What condition can be caused by an excessive amount of growth hormone released by the pituitary gland in childhood?
- A. Acromegaly
- B. Gigantism
- C. Syndrome of inappropriate antidiuretic hormone
- D. Dwarfism
Correct answer: B
Rationale: Gigantism is the correct answer. It is a condition caused by excessive growth hormone release before the epiphyseal plates close, leading to abnormal growth. Acromegaly (choice A) is caused by excess growth hormone after the epiphyseal plates close, resulting in enlargement of bones and tissues. Syndrome of inappropriate antidiuretic hormone (choice C) is characterized by the excessive release of antidiuretic hormone, leading to water retention and dilutional hyponatremia. Dwarfism (choice D) is a condition characterized by significantly below-average height.
5. Cellular swelling is:
- A. Irreversible
- B. Evident early in all types of cellular injury
- C. Manifested by decreased intracellular sodium
- D. None of the above is correct
Correct answer: B
Rationale: Cellular swelling is indeed evident early in all types of cellular injury. This occurs due to the influx of water into the cell, leading to swelling. Choice A is incorrect because cellular swelling is reversible if the injury is not severe. Choice C is incorrect because cellular swelling is not manifested by decreased intracellular sodium; in fact, it is associated with increased intracellular sodium due to water influx. Choice D is incorrect as option B is the correct statement.
